Question

beth recently became a vegetarian. the doctor suggested beth eat more peas and beans to ensure she gets all of the nutrients she needs. which element might the doctor be trying to help her get more of? carbon phosphorus nitrogen

Explanation:

Peas and beans are legumes. Legumes have a symbiotic relationship with nitrogen - fixing bacteria. This allows them to take in nitrogen from the air and convert it into a form that can be used by plants (and then by humans when they eat the legumes). Proteins, which are essential nutrients for the body, contain nitrogen. Since Beth is a vegetarian, ensuring an adequate intake of nitrogen - rich foods (like peas and beans) is important for protein synthesis and overall nutrition. Carbon is present in all organic compounds (including those from non - legume sources like grains, fruits, etc.), so it's not the specific element targeted here. Phosphorus is important for various bodily functions like bone health and energy metabolism, but legumes are not particularly highlighted for phosphorus in the context of a vegetarian diet's nutrient needs compared to nitrogen for protein.

Answer:

nitrogen
